Hello @IEdiong, thank you for participating in Week 4 of Algorithm Fridays.

Your solution works for most test cases, however it fails for the test case for when one of the elements of the array is 0.

prodOfNums([4, 3, 0]); ❌ // should return [0, 0, 12] but yours returns [0, 0, 0]

Also, do you think we can better optimize this in terms of memory usage? Do we have to create a new ans array?

Kudos all the same for a good attempt! Let me know what you think.

Hello @meekg33k, thank you for the feedback.

I did not consider this particular test case, but I must confess that my mind is being expanded as I participate in this challenge.

I did do some brainstorming for a better way that doesn't involve me creating a new ans array, but I couldn't come up with something good. Please I'm open to corrections and suggestions.
